Rum sort of drink (5)
I believe the answer is:
toddy
This clue might be a double definition.
'rum' is the first definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Maybe there's a link between them I don't understand?
'sort of drink' is the second definition.
Can you help me to learn more?
(Other definitions for toddy that I've seen before include "Drink made with spirits and hot water" , "Spirits with hot water, sugar and spices" , "Mixture of spirits, sugar and hot water" , "Palm-tree sap" , "A hot tipple" .)
